Sean Hoare, the former News of the World showbiz reporter who was the first named journalist to allege Andy Coulson was aware of phone hacking by his staff, has been found dead, the Guardian has learned.

Hoare, who worked on the Sun and the News of the World with Coulson before being dismissed for drink and drugs problems, is said to have been found dead at his Watford home.

Hertfordshire police would not confirm his identity, but the force said in a statement: "At 10.40am today [Monday 18 July] police were called to Langley Road, Watford, following the concerns for the welfare of a man who lives at an address on the street. Upon police and ambulance arrival at a property, the body of a man was found. The man was pronounced dead at the scene shortly after.

"The death is currently being treated as unexplained, but not thought to be suspicious. Police investigations into this incident are ongoing."

Whatever the cause or circumstances of Mr. Hoare's death, it is difficult not to regard any death at this stage in the saga as "suspicious."
